In general: light, heat and hardly water.

They look pretty compact to me...

They do look very compact imo, and you mentioned they flowered so they're healthy. Are you fertilizing these?

The only two variables to make things more compact is to reduce watering and fertilizing and bump up temperatures during the day.

But they look great Kevin!
Check out the blogger lithop stories as she grows a number of them as well.

Minty - who is 'she' blogger are you referring to? Does 'she' grow anacampseros too? Kevin grows lithops very well IMO.

Kevin

I wish I could give you tips - but do not know/have this plant. They all look very nice to me :)

Rina

i believe Minty is referring to the blogger who writes a blog called 'Lithops Stories"...

Rina, I included her name ^ and yes she grows anacampseros and number of mesembs very well on her windowsills

It is their growth habit, Kevin, since they do not appear to freely branch. So, if grown properly (full sun, rarely watered and and rarely fed) they will tend to grow slowly along a single stem with very tight and nearly invisible internode. So yours look as compact as it is possible for them to grow.

This is my A. rufescens in 2012:

Descendants today: I prune it regularly because I don't like it snaking around all over. When cut, two to three new rosettes grow around the stump (red arrows) and the tops root easily if you have the patience to babysit them (green arrows). I toss ones that I consider too out of shape.

P/.S. Hey may I ask an OT question? How often do you water your gibbaeum? Mine barely survived last winter and it may die altogether this time around!

Minty

Thanks for the link - I actually read lots of that blog; just didn't see the name/person you were referring to, I would have most likely recognized. Now I realized that you did mentioned blog's 'title'. I guess I am bit thick, expecting the link, or name of blog in quotation marks...

Harry - Might you have some photos of larger Anacampseros from your collection? I'm really curious to see, if you do.

Minty - Rika and her blog are pretty awesome! I do follow it and she has lots of interesting Anacampseros. Many varieties than I've ever seen before. Like nearly all of the photos I've seen online her plants are quite small, which makes it hard to see the larger growth habit. I suppose this is the closest post she has on the subject:

Rina - I'm surprised you don't own one of these yet. They're pretty neat looking and I do enjoy their flowers. I'm not really sure that I grow Lithops well but they are doing alright for me, haha.

Pagan - Very helpful photos. No joke about them being right against your lights. I would have thought they leaves grow flatter rather than out a bit, but I guess that's just the way they are! The new rosette clumps look nice, I'd be alright with mine looking like that after some pruning.

I do find they grow fairly slowly. Overall, they don't seem to really grow or change much, but when I look back on my photos I can see the size difference.

OT questions are fine. =) I quickly dip the bottom of my Gibbaeum pot every couple of weeks to keep the roots somewhat alive. Especially since the plant has buds growing. The old leaves are sort of being absorbed and frankly, I'd like them to all be gone because of the squirrel damage.

Last year I had another Gibbaeum that had too many leaves. I didn't water it nearly the whole winter and then when I finally decided to, it was too late and it withered away. This year I am going to water sporadically and let it absorb some leaves and not go too dry.

Thanks Harry! That is so many more different species than I expected. Your A. retusa laguninisa reminds me of an Ariocarpus.

Now it's confirmed that I'll keep taking care of mine as I have been. =)
